Title: Device for balancing of washing machine
Inventor: PARK YONG SEOK
IPC: D06F39/12
Filed: 1998-11-30
Abstract: PURPOSE: A horizon controller of washing machine is provided to reduce a wrapping material spent in a wrapping of product, to reduce a cost in a transfer and not to generate an interference between a clutch and a bottom installed the washing machine. CONSTITUTION: In installing a washing machine, a horizontal state of washing machine is maintained by controlling an unevenness with rolling an assembly of control leg(4) with considering a state of bottom installed the washing machine after assembling a mount of rubber tow and a rubber tow(5) in rear and lower both sides of silent base and by assembling a leg mount(3) and the assembly of control leg(4) in front and lower both sides of silent base. The washing machine is wrapped in a state separated the assembly of control leg(4), the leg mount(3), the rubber tow(5) and the mount of rubber tow from the silent base. Because a height of silent base is lower than an existing washing machine, a height of wrapped product becomes low. Therefore, a loaded height of product becomes low when the product is loaded in a container. Thereby the load of wrapped product in three stages is able when the product is loaded in the container for export.

Title: Circuit for detecting source voltage
Inventor: LEE SANG YONG
IPC: G11C16/06
Filed: 1998-12-23
Abstract: PURPOSE: A detecting circuit of source voltage is provided to control an output level of source voltage without correcting in a fabricating process of many NMOS transistors to control an output voltage. CONSTITUTION: A memory cell is outputted in a high status through a NAND gate(11) when a high enable signal and a low program signal are fed to read a status of the memory cell(M). A drain terminal of the memory cell becomes a grounded electric potential by turning on a first NMOS transistor(N21) with the high signal. The high signal turns off a second NMOS transistor(N22) and turns on a first PMOS transistor(P21) by reversing to a low state through a first inverter(I11). A voltage about 2V is fed to a source terminal of the memory cell through the turned-on PMOS transistor(P21). A reading voltage is fed to a gate terminal of the memory cell. In reading the state of the memory cell, a current of cell is not flowed when the memory cell is programmed and a sensing node(Q11) is maintained a high status. Therefore, the high signal is outputted. On erasing the memory cell, the current of cell is flowed and the sensing node(Q11) is maintained a low status. Therefore, a low signal is outputted.
